Gunicorn worker定期崩溃：“套接字未注册”

Question

有时（几小时一次）gunicorn worker因以下错误而失败：

[2014-10-29 10:21:54 +0000] [4902] [INFO] Booting worker with pid: 4902
[2014-10-29 13:15:24 +0000] [4902] [ERROR] Exception in worker process:

我用的是：

Python 2.7.6
gunicorn==19.1.1
trollius==1.0.2
futures==2.2.0

有什么想法吗？原因是什么？怎么解决？在

谢谢！在

我在大约一年前报告了一个gunicorn错误，修复应该在gunicorn 19.6.0及更高版本中：https://github.com/benoitc/gunicorn/issues/1258
